Inny: Healthy controls
120 healthy participants (balanced for sex) ranging from 20 to 80 years old will be included.
|
Each participant will undergo 45 min of PET/MRI recording that will begin immediately after an intravenous bolus injection of [11C]ORM-13070 (350 MBq ± 10%) and will last for 45 minutes in a resting state.
During this time, MRI acquisition will include several MRI sequences: 1) One sagittal MP-RAGE sequence of high-resolution anatomical 3D T1-weighted images (5 min); 2) One 3D T2 FLAIR sequence (5 min); (3) One turbo spin-echo (TSE) neuromelanin-sensitive sequence (7 min, Garcia-Lorenzo et al., 2013); 3) One echo-planar imaging (EPI) sequence in the axial plane (15 min duration) to acquire diffusion images; and 4) One 13-min resting-state fMRI run using high resolution T2* weighted gradient-echo EPI sequences covering the entire brain and including the lower brainstem.
A battery of neuropsychological tests will assess cognitive, emotional, and sensory domains linked to noradrenaline function.
Participants will complete the Montreal Cognitive Assessment for global cognitive function, the Digit Span and Free Recall tests for memory, the Trail Making, Tower of London and Stroop tests for executive functioning, Beck Depression Inventory for mood, State-Trait Anxiety Inventory for anxiety, the Epworth and RBD screening questionnaire for sleep, the visual analog and Kings PD scales for pain, the Lille Apathy Rating Scale for apathy, the VOSP for visuo-spatial capacity, the PDFS-16 for fatigue, the UPPS for impulsivity, and the SCOPA-AUT for autonomic assessment.
An olfactory screening (30-40 min) using the extended ODOFIN (BURGHART) Sniffin' Sticks Test battery (Burghart Messtechnik Denmark).
This battery consists of 3 tests: The threshold (T) test has 48 Sniffin' Sticks (32 blanks and 16 dilutions with 2-Phenylethanol) and is used to ascertain the participant's olfactory threshold.
The discrimination (D) test consists of 48 Sniffin' Sticks (16 triplets of odorants) where the participant must tell the odd one out in the triplet.
The identification (I) test consists of 16 Sniffin' Sticks with everyday smells which the participant has to name using a selection card containing four choices.
Together, these make up the TDI score.
